This card's name is a pun on the one of the on readings of the kanji for color (色, しょく, shoku), as it also sounds like the word shock (ショック, shokku). This card is the first Fairy-Type Number monster, as well as the first Number monster to be Forbidden. Coincidentally, at the same time in which this card was Forbidden in the TCG, Number 11: Big Eyewas Limited in the OCG. They were both used by Fortuno. In the anime, when this monster detaches an Xyz Material, it absorbs it into its center horn. Its effect then uses the bigger eyes above its face as spotlights, and reveals face-down cards on the field of the declared type, before launching the center horn on its forehead into the revealed card. Its horn regrows afterwards. The number 16 is shown on the right side of what could be described as the waist of this monster. This monster's initial form somewhat resembles a prism. When the sealed form transforms into its unsealed form, the prism-like form first breaks apart. The broken pieces then destroy themselves and then form the unsealed form of this monster (it first does the mask-like face that is part of this monster's beak and then it forms the rest of the body). This monster appears in the artwork of Summon Gate.
